Re-posting to the RHEL5 list since the RHEL4 list seems to be very quiet... -----
I am trying to determine if this is buggy behavior or just some sort of "feature" of autofs: I have two fixed NFS mounts which are read-only (by design): [root@serverx ~]# grep vol0 /etc/mtab filer1:/vol/vol0 /mon/filer1/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.58 0 0 filer2:/vol/vol0 /mon/filer2/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.59 0 0 If I use autmount via /net/<host> to access the same NFS path, it is mounted read-write (again, by design): [root@serverx ~]# cd /net/filer2/vol/vol0/etc [root@serverx etc]# grep vol0 /etc/mtab filer1:/vol/vol0 /mon/filer1/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.58 0 0 filer2:/vol/vol0 /mon/filer2/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.59 0 0 filer2:/vol/vol0 /net/filer2/vol/vol0 nfs rw,nosuid,nodev,soft,intr,addr=192.168.1.59 0 0 However, I am unable to write to the filesystem: [root@serverx etc]# touch testfile touch: cannot touch `testfile': Read-only file system If umount the fixed mounts and let the automount timeout, and then reacces via /net it works as expected: [root@serverx ~]# umount filer1:/vol/vol0 [root@serverx ~]# umount filer2:/vol/vol0 [root@serverx ~]# grep vol0 /etc/mtab [root@serverx ~]# cd /net/filer2/vol/vol0/etc [root@serverx etc]# grep vol0 /etc/mtab filer2:/vol/vol0 /net/filer2/vol/vol0 nfs rw,nosuid,nodev,soft,intr,addr=192.168.1.59 0 0 [root@serverx etc]# touch testfile [root@serverx etc]# touch testfile [root@serverx etc]# ls -l testfile -rw-r--r-- 1 root root 0 Jun 17 10:37 testfile I can then remount the fixed mounts and it continues to be writable: [root@serverx etc]# grep vol0 /etc/mtab filer2:/vol/vol0 /net/filer2/vol/vol0 nfs rw,nosuid,nodev,soft,intr,addr=192.168.1.59 0 0 filer1:/vol/vol0 /mon/filer1/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.58 0 0 filer2:/vol/vol0 /mon/filer2/vol/vol0 nfs ro,nosuid,bg,addr=192.168.1.59 0 0 grep vol0 /etc/mtab [root@serverx etc]# touch testfile [root@serverx etc]# ls -l testfile -rw-r--r-- 1 root root 0 Jun 17 10:38 testfile But now, my read-only mounts are writable! [root@serverx etc]# cd /mon/filer2/vol/vol0/etc [root@serverx etc]# touch testfile [root@serverx etc]# ls -l testfile -rw-r--r-- 1 root root 0 Jun 17 10:39 testfile I am on RHEL4.8, autofs5: [root@serverx etc]# cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 8) [root@serverx etc]# rpm -q autofs5 autofs5-5.0.1-0.rc2.106.el4_8.4 [root@serverx etc]# ps -ef | grep auto root 3178 1 0 Jun11 ? 00:07:25 automount5 I have replaced host names and IP addresses in this output... Thanks, Kevin
